Description
The whitish-pearly, thin shell is broadly umbilicated. It has a conoidal shape. The 5½ convex whorls are separated by a gradate suture. They are ornamented with oblique, dense regular radiating costellae, and two spiral lirae on the lower part. The body whorl is ventricose, radiately costellate above, with three acute elevated median spiral cinguli, beneath with obsolete concentric striae. The umbilicus is wide, carinated at the periphery, plicate, and denticulate. The aperture is subcircular.
This marine species is finely and closely reticulated ; the whorls are rounded and show no trace of angularity. The umbilicus is not encircled by a keel.[2]
Distribution
This marine species occurs in the Bay of Biscay.
